fix: mismatched ethers types when in esm project

Fix mismatch of ethers/lib.commonjs Provider with ethers/lib.esm
Provider. This has been an issue when attempting to construct
configuration driven provider fallbacks for did-resolver

Drilling down to the Provider type via this package within an esm
package yielded a `lib.commonjs` `Provider` that did not match the esm
ethers `Provider`.

Restructure build directories into `lib.commonjs` and `lib.esm`. Matches
structure in ethers.js

Adjust .gitignore to exclude new out directories

Separated into two tsconfig files named `tsconfig.{common,esm}.json`

[package.json]
Removed `source` [not in spec]
Removed `type`, `module`, and `types` from top level
Added `import` and `require` to `exports` and re-added `types`
Modified `files` to point to new out dirs, removed LICENSE (included by
default), and src (no utility).
Modified script `clean`
Added new `build:` scripts both called from `build`
